IMPROVEMENT IN EXTINGUISHING FIRES IN BUILDINGS.

Specification forming part of Letters Patent No. 98,175, dated December21, 1869.

To all lwhom it 'may concern:

Be it known that I, ORAzio LUGO, of the city and county of Baltimore,and State of Maryland, have invented new and useful Improvements iu theApplica-tion of Steam to .Extinguish Fires in Buildings, 85e., anddohereby declare the following to be a full and correct descriptionthereof, reference being had to the accompanying drawings, making partofvthis specification, and to the letters and numbers of referencemarked thereon, similar letters and numbers being used in all thefigures to denote the same parts.

In these drawings, Figure l shows a section of a building, taken throughfrom front to back.

The nature of my invention consists in so arranging pipes in buildings,and making their outlets easily accessible, that a connection can bequickly formed with the boiler of a steam fire-engine, or with a boilermade portable for that purpose, in case a fire should break out in thebuilding, to extinguish it by means of steam.

That others may be enabled to understand and make use of my improvement,I will proceed to explain it.

A A are the walls of the building. B B are the tloors, dividing thehouse into stories. C C are partition-walls between the rooms.

a is a pipe, suitable for conveying steam, extending from the outlet aup in the wall to the upper story, where, if there is more than one roomin the story, the pipe is carried across the building, and outlets s sare made in the pipe, one in each room. b is another pipe, extending, inlike manner, from its outlet b up through the wall to the second story,across which it runs, and outlets o o are made in it, as in the pipebefore mentioned. c is a third pipe, having itsoutlet c below theothers, and extending up into the iirst story across the building, andhaving outlets tt like the rst and second pipes-that is, one for eachroom on that floor.

This order of arrangement for the outlets on the outside is adoptedbecause it shows by their position to what part of the building thedifferent pipes lead 5 but they may be differently arranged andnumbered, or otherwise marked, to show which pipe leads to anyparticular story.

rIhe pipes are shown as being built into the walls; but in applying theimprovement to a building already erected, the pipes may be carried upin the corners of the rooms, or where they will be least in the way.

The operation is as follows: In case of the building getting on fire inany part of it, the steam 'tire-engine immediately upon its arrival hasa connection formed between its boiler and the outlet of the pipe thatleads to -that story of the building in which the re has started bymeans ofa pipe and union-joint, so called, and, steam being turned on,that room or story will be illed at once, and the tire extinguished bythe steam expelling the air, and without any risk of damage to the goodsor premises that water generally produces. The steam will also penetrateinto places between bales ofgmerchandise, Snc., where water cannot beapplied.

I am aware that arrangements are sometimes made in manufaotories usingsteampower whereby steam could be turned into any part to extinguishfire, but

What I claim as my invention, and desire to secure by Letters Patent,is-

The arrangement of pipes and outlets to the same, substantially asherein set forth, in connection with the application of steam from asteam tire-en gine or portable steam-boiler.
